You shut off the gas.
Shut off the power.
Remove the gas valve and burner assembly.
After cleaning and reassembly you must purge the system and use a gas leak detecting soap to verify no leaks before turning on the power.

Do you have a good pilot flame? Is it wrapping around the thermocouple good? You may need a new pilot orifice.

Heater is not igniting


see this causes and fix it. God bless you
f there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below). If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.
If the furnace makes a rumbling noise when the burners are off, clean the burner and adjust the burner air shutter.
If the air is too dry, wash or replace the evaporator pad if you have a humidifier; test the humidistat; and adjust the water-level float to raise the water level.
If some rooms are too cool and others too warm, the distribution system may require balancing. Refer to the Forced-Air Distribution Fix-It Guide .

Hi and welcome to FiXya I am Kelly.

Your pilot light burning yellow is a sign of a dirty orifice. This can be caused by insects or a spider web in the pilot air supply.
To clean the air supply / orifice area see this page:

http://www.nexgrill.net/trouble/p1.5.html

Also the thermocouple may not be close enough to the flame. You won't know this for sure until you finish cleaning the pilot / orifice area.

This link has step by step links for all of the components / causes of a pilot not staying lit. Click each of them and it will bring up a pdf file with step by step instructions and pictures:

http://www.nexgrill.net/trouble/p3.html

A bad thermocouple can also cause this. Givien you have a yellow flame I do not think this is your problem. But if it ends not staying lit after cleaning see this page on how to get to the thermocouple:

Thanks for choosing FixYa.

Pilot light will not stay lit on model 465FX-R wall mounted gas furnace. Thermocouple was replaced but still won't stay lit. Gas is on at the meter. Any suggestions?


It is possible that gas valve is bad, however, try replacing the pilot orifice located in the pilot assembly. If the flame is inadequate it will not generate the voltage required in the thermocouple. Pilot orifices are less than $10 and can be found at your local heating contractor's parts counter. Bring in the orifice to match.

Pilot wont stay lit installed new gas valve and new thermocouple


Is this a standing pilot furnace, or electronic igniton?

If standing pilot, does the heater use a fan to blow air through the heat exchanger?

If the answer to those questions is yes, then check that the pilot orifice is not partially plugged and that there is a strong pilot blowing against the thermocouple. If there is, replace the thermocouple. If not, check the orifice again, and check that the inlet screen to the gas valve is not filled with gas line trash.

If the the pilot flame is good and it continues to go out, the thermocouple magnet in the gas valve may be weak. Replace the gas valve as to get just the magnet and coil is not easy.

Reply back any questions you may have.

Furnace pilot problem


check the pilot gas pressure, might be too weak and blowing out when the blower starts, the clicking noise is the gas valve shutting down when it detecks no pilot flame, that park is normal.

The pilot orifice could be dirty causing the pilot flame to be too small. Unscrew the pilot tube at the pilot assembly. The orifice is inside. Remove the orifice and blow it out with compressed air only. Reassemble and see if that fixes the problem. If the pilot flame is set too low, sometimes opening a door will cause a draft to blow out the pilot. If the thermocouple is good and the pilot flame is set properly, the control valve may be bad.
